Thinkpad 755cx & Mwave

Archived from groups: comp.sys.laptops (More info?)

Hello,

I've been working on/with PC's for many years (since '84), but never messed
with Laptops/Notebooks very much, so all this PCMCIA, PC Card, etc. laptop
stuff is new to me.

I picked up an old IBM Thinkpad 755CX this past winter just to tinker around
with.

Would someone help me identify the model of this old IBM Thinkpad 755cx.
It's a Pentium-75 w/ 540mb HD and 24mb of RAM running DOS 6.22 & Win 3.11.
It's got a Floppy Drive, but no CD Drive. I'm trying to find out more
about the soundcard(?). I noticed that the Users Guide that I downloaded
from IBM's website shows a modem/sound card with 3 jacks (Headphones, Mic
and Modem)... this one only has 1 jack with a music note. What is it?

I've tried everything I can think of... Fresh install of DOS & Windows,
downloaded and installed all the drivers from IBM's website
(http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=DSHY-3PLMY2)
, but still don't have any sound. Anytime I try to access anything
sound-related, I get an error message saying that the Mwave Sound System
Mixer is not currently installed. I've tried re-installing it, but it
doesn't fix the problem. The instructions said to install the Midi Samples
before installing Mwave, but I got an error telling me that Mwave hadn't
been installed -- so I installed Mwave and then re-installed the Midi
Samples.

One more question... are these Type I or Type II PCMCIA slots??? All of
the website with TP 755cx specs say Type I/II, but one IBM dealer tells me
it's only Type I, while another IBM dealer tells me it's Type II.

Thanks!

I had (still have, but no longer use) a 755CX. Mine had a 800x600 res
display which I don't think was common to all of them, but I don't
remember. It originally came with a dual boot configuration which they
called Selectasystem (I think). This had DOS/Win 3.11 as one choice and
OS/2 Warp v3 with WIN-OS/2, (meaning it would run Windows 3.1 and its
applications from OS/2, as the other choice. I eventually replaced all
this with Windows 95 and then Windows 98. I recall this to be the best
way this computer ran for me until I replaced it with something newer
and faster.

You must install the Mwave modem in its entirety for the sound system to
work as it should, but I suggest you try doing this with the Windows 98
files etc. if this OS is available to you. I know it had the fewest
problems on my 755CX.

I haven't looked at it for a while but mine still worked the last time I
tried it!
